ELECTRIC SIGNALING APPARATUS AND CIRCUITS.

Application filed July 5, 1889.

To all 207mm it may concern:

Be it knownthat I, FELIX BENEDICT HER- zoo. Ih. D., a citizen of the United-States, and a resident of the city, county; and State of New York, have invented a new and useful Improvement in Electric SignalingApparatus and Circuits, of which the following is a specification.

Myinvention relates'to an organization in which apparatus is placed at a number of stations connected in series by less than as many wires asthere are stations. Its object is to enable the central or controlling station at one point in the series to pick out or individualize anyone of the other stations and to produce at these stations any desired results, including, for the sake of example, the ringing of an alarm, or the release of a latent signal transmitter or teleseme, or the product-ion of any desired effect.

The teleseme is the generic name of the signaling apparatus shown in numerous patents to me. In some cases this is operated by a motor normally held lockedand re leased by a detent under control of a magnet brought into action from the releasing or Specification of Letters Patent.

Patented May 6, 1913. Serial No. 316,643.

which such a station designating or characteristic signal is produced, in. addition to the variable portion which may be set, at will, to produce any one of a number of different signals.

The figure represents the organization showing two of a number of similar individualizers placed in series on a single circuit, these being controlled from the central station, shown in the lower part of the drawing and marked Central. 1

The apparatus here includes as .elements the keys 0, P controllingcurrents of opposite polarity, the key O controlling a current of abnormal strength;.Q. an indicator of any suitable construction for receiving the signal from a transmitter or responder at the distant station; N, a simple 7 bell, acting as a detector to show whether the mereased current is sufficiently strong. Preliminary operation: IVhen the central ottice operator wishes to call up a particular station, he presses key 0, and the current passes from earth 44, key P, line 43battery 4:), bell N, line 46, key-contacts O and O, thence by line 5 to the apparatus at the nearreceiving station. This form is the spring I est station; here it enters polarized relay B,

actuated form but in other instances the apparatus is not under stress of a motor spring but is directly driven as for instance by a step magnet. A patent showing an appa ratus of the first form is 289,834, and one showing the second form is 292,115; another is shown in my Patent 696,140. I

It consists further in adapting to apparatus constructed to perform the acts described responding or verifying apparatus, which will operate to echo back, as it were, to the controlling station whether the designed .operation has been correctly per formed, thus serving as a checkupon maloperation and defects due tothe apparatus or the wires.

In the following descri tion (and the drawing) K, K and K" Wlll be considered the elements of the device which it is intended to operate at such sub-station, and when it is desired to add to the system the verifying or checking 't. ure, to which reference has been made, these elements K, K and K ill be considered as a latent signal transmitter adapted to send a signal which is recognizably diti'erent foreach one of the stations. Such a form, for instance, .is'shown in said Patent 696,140, F igure 6, in

l It I l l l l i l l I l i l l l i i i l the armature A of which makes normal contact with A and the current for the'first- '(which israt all times in contact with the metal contact surfaceoft the roller) will be bridged to thespring X (which in the abnormal or working position illustrated in the drawing shows an insulated space. brought to'a position in which such'bridging is prevented). This metallic piece is so arranged that at suitable points of revolution of the roller, it will successively connect the direct or main contact spring E with the branch springs E, E and X, and thus successively control the separate functions performed by the respective branches 14, 21 and 17. From the spring X the current passes through the small resistance M" .to the line and out to next station by way of wire 17, 16 and 8,- thence through a; simila organization for each subsequent'station and 'finally to asuit able return as indicated by the final ground a at end of wire 11, or if the station selected .should be the last upon the line the ground a would of course be located thereat. But this rent will pass through magnet C, relay armature, A, line and out to the next station, and, at eachimpulse through the magnet G,

this will control any suitable device, as the the number of impulses required to brlng which of course,

step-by-step wheel D by means of the cooperating pawls and adjuncts. This wheel is connected with the contact roller D, (these parts being shown separately in orderv that the circuit connections may be more readilytraced, connection being indicated by the spindle N). As the result of this organization, the central office, by pressing key 0 a certain number of times may bring the roller ,D into any definite position. The contacts on the roller are so arranged with reference to the bridging of the contact springs pressing thereon, that at a given number of steps from zero, (this number differing for each of the stations in series) the roller will be brought into the posltlon shown in the draw m 7 Pout-rolling operation: After having given any desired station-roller into this position,

the central'op'erator presses the key P, thus changing the polarity of the current and causing the re ay-armatureto again make contact with A, whereupon the current passes to spring E and spring E, operative magnet K" of teleseme, and the linethis releases the teleseme, and the signal composed of a number of makes and breaks, do'not aflect the polarized armature, will be received on the indicator Q. After passing through the teleseme, by way of its magnet K, its wheel K and its spring, K, the current will pass up branch 16, out to the next station, taking the same course therein as in station 2, excepting that, as in no other station are the roller contacts in the same position, the current will at this station pass through the resistance M" instead of through the teleseme or other indiiridual apparatus thereat as referred to beow. r

Restoring operation: When it is desired to return the commutating rollers to ,zero, the key 0 is pressed a number of times, thus actuating the magnet O and b it the roller until the latter is stopped y a pin I"-engaging with the pin J carried by the roller. At this point the branch spring E arranged to cooperate only yvith the unison cont-act, (shown over this spring in the drawing) having the same relative posit-ion on each roller, is bridged into circuit, and

X and E the two other branch springs springs free;

are cut out; and when this-is'done and central key P is pressed, the current will actuate the relay armature once more, and passing through the magnet C" will cause this to attract resetting armature F, thus disengaging the clicks from the ratchet and permitting the roller to return to zero by stress of spiral spring J on the step-by-step wheel. But immediately before the clicks are disengaged, the armature F makes contact with spring M inthe following circuit (5, 3?, 6, A, A, 23, armatures F, F, spring M, 15, 13, magnet C and out as before), thus, by offering an alternative path to the current, preventing a break in the circuit through the roller as this returns to zero; and, further, to prevent this return movement from short-circuiting the magnet Q, the resistance M" is placed where shown.

Summary: Normal position at substation;

relay armature at A spring E on roller at all times, spring X bridged to it; other tracts polarized armature A and this breaks polarized shunt at A and steps the roller which is actuated by the motor magkey 0 (weak+current) atv r net C forward one step for each closure through motor branch leading from X, M, 17, 16, and out. At prearranged step (for instance sixth) key P (strong 'current) closes short circuit around motor magnet C preventing its subsequent operation and at this point the theretofore closed branch through spring Xis broken and spring E" has substituted for the same, and connected into action the working branch-21 upon which teleseme, or any other mechanism 'which is to be thus actuated or controlled,

located. Unison is provided as a preliminary to restoration by again using key 0 (weak-t-c-urrent) agamshunt-ing in motormagnet C" and.causing a sufiicient' number of steps to complete its cycle or a greater number to allow for accidental failures whereupon spring E throws into circuit res- 'toration branch 14 andmagnet C (but not actuating the latter) restoration is effected by an impulse on key P (strong-) again closing short circuit around motor magnet C" and energizing restoration magnet G, freeing the clicks on motor and permitting its spiral spring to restore it; continuity of circuit during this recoil of motor (which would reopen circuit at spring E before completion of return, and thus would pre-. vent restoration magnet from completing its work) is secured by branch through 15, M?, F", F, 23 and armature A of polarized relay.

The followin conclusions are to be noted among others t at will occur (to the expert l'oo who examines) as incidental to the operation of the organization described.

1. As many stations as desired may be successively operated either. to produce the operation of their local devices or to produce the respective return in verification signals.

2. The successive controls over the responding or verification transmitters -may be made to produce such verifications or not according to the type of such verification apparatus e. it being assumed that it is in all cases of the latent signal type. The production or non production of such a response will depend upon whether or not the teleseme in a given controlled station has been locally 5 set or arranged to respond or not.

3. Such response may include in addition to the verification such further variable signals as may be within the selective range of the transmitter.

It has been stated that the purpose of this general switching mechanism is to enable an operator at another station to produce at the station at which the switching apparatus is located, desired eifects other than those of ringing an alarm or the release of a teleseme, and for the production of such eiiects, as indeed'for the operation of some types of alarm or teleseme or the operation of the modified form of the station switch which was illustrated in the specification as originally filed herein as a species of the broad invention, an increased strength of the same polarity of current as supplied by battery is needed. Key 0, battery 47 and ground as show how this may be added where needed without interfering with the rest of the arrangements. -When this is to be brought into use both of the keys 0 and 0 must be depressed. When the operator at the central station is not operating the keys 0 and P to release and receive a signal from an outlying station the circuit --from the outlying stations is completed through the central station through the switch contact O'wire 4 key P wire 3 bell P and wire 2 to ground. Hence attention of the central operator can be called through the bell I from an outlying point by throwing current on to the line.
